Information modelling using RDF. This note describes some ways that contexts might be used to facilitate creation of RDF descriptions of complex objects and concepts. (For historical reasons, this is in PDF rather than HTML: I haven't mustered the energy to convert it yet. Sorry!)

RDF for end-to-end content. Notes from a presentation to our development team about why RDF should be considered for application data formats.

Notes about representing facts and rules in RDF. These are written with the RDF expert system shell in mind, but have some wider implications for reference-without-assertion (traditionally, reification) in RDF. (Work in progress at 2-Dec-2002.)

Using datatype-aware inferences with RDF: this explores options for incorporating datatype aware inferencing mechanisms into my Swish software. It also contains a brief survey of inferencing constructs implemented in other RDF systems. (Created 5 November 2003, work-in-progress).

History

Semantic Web History: Nodes and Arcs 1989-1999, The WWW Proposal and RDF. A note by Dan Brickley that references Tim Berners-Lee's original WWW proposal, showing how the ideas of RDF were anticipated from the outset of World Wide Web development. http://www.w3.org/1999/11/11-WWWProposal/.

A story about RDF and XML. A position paper by Dan Brickley and Eric Miller about the relationship between XML and RDF: http://www.w3.org/2001/06/rdf-xproc/1. (Note the two bullet points in the section Happy Endings?.)

The Semantic Web: 1-2-3: http://www.disobey.com/detergent/2002/sw123/. Morbus Iff's tale of learning about RDF, explaining with some feeling the tension between RDF's ugliness and its utility. Also contains useful links to related introductory material.

Living with CLASSIC: When and How to Use a KL-ONE-Like Language, Ronald J. Brachman, Deborah L. McGuinness, Peter F. Patel-Schneider, Lori Alperin Resnick and Alex Borgida, abstract and link at: http://www.ksl.stanford.edu/people/dlm/papers/living-with-classic-abstract.html. This paper provides useful insights into the style of description logic that underlies the design of DAML+OIL, and which will presumably be incorporated into W3C's Ontology Web Language (OWL).

A P3P Assurance Signature Profile, Joseph Reagle, W3C Note 2 February 2001, http://www.w3.org/TR/xmldsig-p3p-profile/. This note discusses use of RDF in an XML sigtnature to convey ionformation about the assurance that is intended to be conveyed by the signature.

RDF applications

Public draft of CC/PP structure and vocabulary document: http://www.w3.org/TR/CCPP-struct-vocab/. This proposes an application of RDF for profiling device capabilities and user preferences to be used for content adaptation.
